Coulomb friction; nonlinear dynamics; friction induced vibrations; bistability; adhesion; contact mechanics; tribology;

Dear Colleagues,

In the last twenty years, tribology and nonlinear dynamics have included several major contributions related to key topics such as rough contact, friction, damping mechanisms, and dynamical behaviour of nonlinear systems, which are paving the way for future engineering challenges. The two fields are largely intertwined as, among the others, contact nonlinearities are almost omnipresent in any technical application ranging from the development of NEMS/MEMS to bioengineering, automotive, civil/mechanical industry, and aerospace.

Our recent study through molecular dynamics simulations represents a new approach to improve the mechanical behaviour of nanoporous silicon through controlling the pore shape. In this work, a high strength and ductile structure is obtained for honeycomb nanoporous strucutres.
